▌“If you want to be rich，Build the road first”。With the development of the times，Part of the expressway built by the state in the early stage.、Railway、Regional road transport networks such as high-speed railways have been unable to meet local transport needs.，Its traffic capacity、Service level and other aspects are stretched.，Development of tourism resources、Radiation effects such as utilization and economic development are also gradually weakening.，Road reconstruction and expansion is imminent。
▌For expressway，Road reconstruction and expansion mainly include road widening.、Horizontal and vertical linetype adjustment、Splicing of new and old roadbeds, etc.，The most important thing is to consider the splicing of new and old roads according to the terrain.。Required by the construction unit“Meet a mountain and open a mountain、Bridge in water”，Therefore, the equipment requirements for capital construction are relatively high.，Strict requirements for the quality of concrete。On the joint part of the new and old roadbed，The use of geosynthetics can effectively enhance the connection between the old subgrade and the spliced subgrade soil，Improve the tensile strength of the subgrade at the splicing part、Shear strength，Limit and coordinate the deformation of subgrade soil、Homogenized load，Enhance the overall performance of new and old roadbed。Shantui Jianyou's Concrete、Asphalt mixing station and other equipment can fully meet the requirements of construction units for the use of various grades of concrete.。
▌As the earliest large-scale state-owned backbone enterprise producing concrete mixing and conveying machinery in China,，Shantui Jianyou has long been committed to the production of various types of mixing machinery.，It has witnessed the changes and vigorous development of national infrastructure.。Production of high-quality Concrete Mixing Plant、Concrete mixer Truck、Asphalt Mixing Plant、Stabilized Soil Mixing Station and other equipment shall be used for field construction.、Urban construction and other aspects。The Three Gorges Dam、Beijing-Shanghai high-speed railway、Hong Kong-Zhuhai-Macao Bridge、Beijing Daxing International Airport 、Beijing-Zhangjiakou high-speed railway、Yanchong Expressway、Sichuan-Tibet Railway、And many other roads are under construction.，They all have their shining and heating figures for the national infrastructure construction.。
Construction Force in the Reconstruction and Expansion Project of Dongqing Expressway
▌Expressway from Dongying to Qingzhou.（Hereinafter referred to as:Dongqing Expressway）It connects Beijing and Tianjin.、The Golden Passage of Jiaodong Peninsula。Its reconstruction and expansion project was established in 2021.，From Kenli North Interchange（Main line andG516 Crossover position）600 meters south，North to Dongying Yellow River Bridge，It stops at Beikoubu Town, Qingzhou City，It runs through the north and south of Dongying City and connects with the north of Qingzhou City of Weifang.，To ease the pressure of local road traffic、Play an important role in promoting the economic development of the Yellow River Delta。
▌With high quality product performance，Strong and durable market reputation and measurement accuracy higher than the national standard.，Shantui Jianyou 1 setE3R-120 and 1 setE5M-The 180 concrete mixing station is selected by the construction unit，Applied to the reconstruction and expansion project of Dongqing Expressway，Provide high-quality concrete for project construction，Play the responsibility and responsibility of state-owned enterprises.。
Yanwei high-speed expansion project to achieve customer satisfaction
▌Yanwei Expressway was completed and opened to traffic in 1994.，Up to now, it has served for nearly 30 years.。Limited by the technology at that time，The original design standard of the road is low.，And has long operation time.，Level of road area facilities、The technical conditions of bridges can not meet the existing expressway construction standards.，Reconstruction and expansion is imperative。
▌The total length of the reconstruction and expansion project of Yanwei Expressway is 47.022 kilometers，Constructed according to the standard of two-way six-lane expressway，It starts from the intersection of Rongwu Expressway and Huancui Road, Huancui District, Weihai City.，It ends at the east of Yantai Hub Interchange in Laishan District, Yantai City.，After its completion, the traffic capacity and service level will be greatly improved.，At the same time, it will achieve seamless connection with municipal roads.，Promote self-driving tourism and city image along the line.，To improve and optimize the structure of regional expressway network，Promote the implementation of the layout strategy of Jiaodong Economic Circle、It is of great significance to promote the integrated development of Yantai and Weihai.。
G5. The construction of Guangyuan-Mianyang Section of Beijing-Kunming Expressway is responsible for the expansion project.
▌GThe expansion project of the Guangzhou-Mianyang section of the Beijing-Kunming expressway is to connect Sichuan Province with Chengdu、Deyang、A New Passage between Mianyang and Guangyuan，It is also the southwest region leading to Central China and North China.、Another shortcut for Beijing-Tianjin-Hebei。Its construction can not only effectively alleviate the traffic pressure of the existing Chengdu-Mianyang-Guangzhou expressway,，Effectively reduce traffic congestion、And that transportation efficiency is improve，It can also promote balanced regional development.，Promote local formation“One stem and many branches”Develop a new pattern。
▌In project expansion，Shantui Jianyou 1 setE5R-120 and 1 setE5R-Installation and commissioning of 180 concrete mixing station completed in Guangyuan, Sichuan，Smooth ash discharge，Apply to project construction。With modular design、Convenient disassembly and assembly method、Flexible site layout and other advantages have won praise and praise from customers.，It has contributed to the national infrastructure.。
Shenyang-Dandong Railway Relocation Project
▌Shenyang-Dandong Railway Relocation Project is an important Pre-project of the second runway construction project of Shenyang Taoxian International Airport.，After successful relocation，Land space will be released，To meet the construction needs of the second runway of Shenyang Taoxian International Airport，At the same time, improve the transportation infrastructure in Shenyang.，Promote the establishment of hub cities。
▌In order to ensure the project construction，The service personnel of Shantui Jianyou at the construction site in Shenyang, Liaoning Province shoulder the heavy burden bravely，Adjust the installation plan in time according to customer's requirements，Ensure the customer's production schedule needs。With their efforts.，Shantui Jianyou 2E5R-Successful trial production of 180 concrete mixing station。With the efficient mixing main machine、Supporting various feeding process technologies、Structure of Pressure Scale and Measurement of Coarse and Fine Weighing，It effectively guarantees the improvement of customer production efficiency and the accuracy of measurement.，Provide high-quality concrete for project construction，Gain construction time for the customer，Value is created。
▌Both roads and railways have contributed to the progress of society.、Economic development and people's needs play a decisive role.。Seventy years of wind and rain，As an old state-owned enterprise,，Shantui will closely follow the leadership of the Communist Party of China.，Continue to contribute to national infrastructure construction with responsibility and perseverance，Play the role of the main force of construction with a high-spirited attitude。
